358021 ÷ 17 
Our goal is to divide 358021 by 17.

Let's proceed to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 17

On to step 2:
17 goes into 35 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 34 away from 35, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 17

Advancing to step 3:
17 can be fit into 18 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 1 after subtracting 17 from 18.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 17

Going ahead to step 4:
10 divided by 17 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 210.0
If we take 0 away from 10, we end up with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 17

Let's proceed to step 5:
If we divide 102 by 17, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2106.0
If we subtract 102 from 102, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 17

Advancing to step 6:
If we divide 1 by 17, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 21060.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 17, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 21060.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 21060.05
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 21060.058
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
When dividing 140 by 17, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 21060.0588
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 21060.0588 with a remainder of 4e-05.
